- Check the power: Verify the radio is receiving power. A blown fuse could be the culprit.
- Check the input source: Make sure the correct input source is selected (e.g., radio, CD, AUX). Try switching between different sources to see if any produce sound.
- Check the speakers: Inspect the speaker connections for any loose wires or damage.
These preliminary checks can often resolve simple sound issues. If your bmw 328i radio no sound problem persists, let’s move on to more advanced diagnostic techniques.
